APPARATUS FOR MAKING PAPER CASES FOR INCLOSING CIGARETTES, &c.

SPECIFICATION forming part of Letters Patent N o. 524,988, dated August21, 1894. Application tiled May 17,1893. Serial No. 474.495. (No modell)Patented in England January 4, 1890,1lo. 183.

To all whom may concern:

Be it known that we, RICHARD DALTON and HENRY HERBERT WILLS, subjects ofthe Queen of Great Britain and Ireland, and both residing in the cityand county of Bristol, England, have invented certain Apparatus forMaking Paper Cases for Inclosing Cigarettes or other Articles, (forwhich We have obtained a patent in Great Britain, No. 183, dated January4, 1890,) of which the following is a specification.

The object of this invention is to provide a simple machine which willrapidly and efficiently manufacture cases for inclosing cigarettes orother articles. j A

According to this invention on an endless band there are carried platesor blocks to suit the size of the interior of the case to be made. Tothis band paper blanks are fed either by hand in separate pieces or froma roll orcontinuous supply cut into proper lengths by a cutter providedon the machine so that` the inner end of each blank is situated betweenone 'of the said plates or blocks and the band, the proper position ofthe blank being insured bya stop. As the band moves round, each blank isfolded over its block by coming against a guide or folder in proximitythereto. By the further movement of the band the blanks and blocks arepassed between other folders which fold down the side portions, th erebeing in proximity to these latter folders a pasting or cementing deviceby which paste or cement is applied to the folded edges.v As the casesthus formed and cemented are carried upon their blocks still fartherthey pass between bands, springrollers or equivalent devices (preferablyheated) so that the edges are held in place till the cement is driedsufficientlyA to enable the cases to retain their form. i On the stillfurther movement of the lband the formed cases are removed .from

which block then travels forward to receive another blank and so on.VThe band may carry any convenient number of these blocks.

In order that the said invention may be fully understood we now proceedto describe the bestmeans with which we are acquainted of carrying thesame into practical eifect and for that purpose shall refer to theseveral figures on the annexed sheets of drawings the same lettersandfigures of referenceindicat.

A is the main frame of the apparatus car' rying in bearings B the maindriving shaft C which may be driven from any suitable prime mover by`astrap passing round thel pulley D. On the shaft C is a pinion E gearingwith a spur wheel F on a stud G and transmitting motionthrough a spurwheel G2 to a shaft H. Onthe shaft H is mounted a drum or pulley H2having a groove in its periphery for the reception of an endless steelband I the said band also passing round a similar drum or pulley Hix ona shaft G3 at the opposite end of the apparatus. At suitable intervalsalong this endless band I are loosely connected plates K upon which thepaper cases are formed. The paper blanks (one of which is shown in Fig.la),to form the cases are fed singly by hand or otherwise into a hopperL which conducts the blanks into position between the plates or formersK and the endless band as shown at M Fig. l, each blank as the band`travels round the drum H3 being held between the said band and theformers with a portion projecting in front of the former sufficientlylong to form one side and the bottom of the case. As the blank held bythe formermo vesforward, the end of the overhanging portion of the blankis raised which `may be done by causing it to rest on a projection fromthe band just in advance of the forward edge of the block but preferablyby projections O on the under side of the band I acting onleversN so asto cause the end of the overhanging portion of the blank to be raisedabove a stationary rod or IOO IIS

bar P as shown in Figs. 7 and 8 and by dotted lines in Fig. Yl so thatas the former passes beneath the said bar or rod the projecting portionof the blank is folded along the line 1-2 Fig. la onto the top of theformen The former with the blank thus folded thereonto passes thencebeneath a roller 'Q which holds the blank securely on the former whileprojections a. from opposite sides of a trough or passage S throughwhich the former next passes, press inward the projecting portions 8 ofthe blank, on the front or advancing end of the former, to form thecorners'of the bottom of the case.

At the mouth or entrance to the trough or passage S are inclinesR asshown in Fig. 3 which as the former with the blank thereon advances turnup the projecting edges 4 of that portion of the blank which is situatedbetween the former and the band I. The overhanging edges 5 of the topportion of the blank are then pasted by coming into contact with disks T(shown in Fig. 4) rotating in a trough V containing paste or othersuitable cement or adhesive material. These disks receive motion fromthe main shaft C through the pulleyUand driving band U2 and as theyrevolve in the paste or the like they are continually coated with a filmthereof which they transfer to the under surface of the overhangingedges 5 of the upper portion of the blank as they move in contacttherewith. The former with the partly formed case thereon movingforward, the projecting pasted edges 5 of the upper portion of the blankare turned down or folded over the turned up edges 4 of the lowerportion of the said blank, by inclined surfaces W formed on a piece orcover X (see Fig. 5) of the passage or trough S. This trough or passageis heated from below by means of a gas burner Y as shown, or by anyother convenient means so that as the formers with thecases thereon passthrough this passage the paste by which the parts are connected arethoroughly dried, and to insure the pasted part-s being held in contactwhile passing through the trough or passage, endless bands Z arearranged to travel edgewise on opposite sides of the trough and are`pressed against the sides of the cases on the formers by plungers l)acted on by springs asshown in Fig. 6. The bands Z are carried onpulleys c e2 which are driven by a gut or band d passing round pulleys eon the frame A and pulleys f connected with the pulleys `c. To preventadhesion in case of any paste or gumv having escaped to the surface ofthe bands Z it is preferred to drive the said bands at a speed slightlydifferent from that at which the cases and blocks are traveling. Theformers with the cases thereon as they pass from the trough or passage Spass round the drum H? and enter thence between two disks g mounted on ashaft h. These disks are faced with or have attached to their innersides, surfaces of india rubber or equivalent material aga-inst whichthe edges of the cases are caused to bear when passing between them andas these disks are caused to travel or rotate at a considerably greaterspeed than the band I they drag the cases od the formers as they passbetween them and deposit them into a receptacle placed in posivtionbelow to receive them a stationary spring blade Z being arranged betweenthe disks to detach the cases therefrom. Fig. lb shows in perspective afinished case.

The disks g may be driven at the required speed from any suitable partof the machine or from any other available source; in the drawings theyare shown as being driven from the shaft H by a gut or band z' passinground a pulley k on the said shaft and round a cone pulley k2 on theshaft carrying the disks.

m are scrapers for removing any paste that may get onto the bands Z.

n is a grooved roller situated between the disks g to guide the band Ibetween the said disks to insure the cases being removed from theformers Having now particularly described and ascertained the nature ofour said invention and in what manner the same is to be performed, wedeclare that what we claim is- 1. In apparatus for making cases forinclosing cigarettes or otherl articles, the combination of an endlesstraveling band carrying formers to suit the size of the interior of thecases to be made, with means substantially as described, for firstfolding the blanks over the formers to form the seamless bottom andmeans substantially as described for then turning in the ends of thebottom and folding over each other the edges of the two seams at the-opposite sides of the case, and pasting devices for the said edges,substantially as set forth.

2. In an apparatus for making cases for inclosing cigarettes or otherarticles, the combination of an endless traveling band carrying formers,a frame provided with a trough through which the formers are adapted topass, the sides of the said trough being provided With stationaryprojections and inclines substantially as described to fold the blankson the formers to form the seamless bottom, turn in the ends of thefolded bottom and then fold over each other the two seams of theopposite sides ofthe case.

3. In apparatus for making cases for in-V closing cigarettes or otherarticles, the co mbination of an endless traveling band carryingformers, with disks g between which the formers with the cases thereontravel and by which the cases are removed from the formers,substantially as described.

4. In apparatus for making paper cases for inclosing cigarettes or otherarticles, the combination of an endless band carrying formers, with thelever or levers N and bar P for raisiug the end of each blank andfolding it over its former, substantially as described.
